hpplioation filed July 21, i902.

To all whom it may concern 7 l I Be it known that we, GEORGE O. ROBERTS and HENRY S.WILGOX, citizens of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Starching Machines, of which the following is a specifi-. cation, reference being hadtherein to the ac companying drawings. h

This invention relates to starching machines, and has for its object to provide a construction in which 'all of the movable parts are adapted to be simultaneously raised from the starch-chest and also to improve the driving mechanism and other details of construction embodied in the machine, as hereinafter set forth, and defined by theappended claims.

In the drawings, Figure 1 is a side elevation of the machine; Fig. 2, a vertical section thereof on the line 2 2 of Fig. 1; Fig. 3, a detail elevation of the foot carried by the swinging frame; Fig. 4, a perspective of the hood for the driving-gear; Fig. 5, a plan-of the driving-worm and clutch; Fig. 6, an end elevation thereof; Fig. 7, a detail elevation of the locking device between the swinging frame'and base; Fig. 8, an end view of-the same part; Fig. 9, a horizontal section through the bearing for one of the tension-rollers, and

Fig. 10 an elevation of a modification of the securing means between the swinging frame and base.

Like letters of reference refer to like parts in the several figures of the drawings.

The base or standards A, upon which the machine is supported, may be of any desired shape and are located at opposite sides of a starch-chest B, which is provided at its lower portion with a drain or draw-0E cock B, I while the standards forming the base are connected together at suitable points by means i of tie-rods A. At the upper portion of these standards a receiving-table A is located at one end and a delivery-table A at the opposite end, while between these tables a swinging frame 0 is suitably mounted upon a pivot C to rest upon a base A .The starch within the chest B is adapted to be heated by means of a steam-inlet pipe B disposed at the Serial No. 11e,47o. (No man.)

upper end of a condensing-chamber B the lowerfend of which is provided with an exhaust-pipe B Leading from the upper portion of the chamber B is a steam-pipe B provided with aregulating-valve B from which a perforated injecting-pipe 13 extends laterally across the lower portion of' the starchchest for the purpose of agitating and heating the starch therein;

The starch-chest is entirely free of any of the operating mechanism, all of which is mounted upon the swinging frame 0, as shown by dotted lines in Fig. 1, wherein the main starching-roll C is suitably j ournaled in a depending portion of the frame and has disposed concentrically thereto a series of auxiliary rolls C positively driven bya suitable pinion C, Fig. 2, upon one end of the roll 0 engaging similar gears on rolls G which may be of any desired construction, preferably fluted or corrugated, as usual in this art. The starching-roll O is driven by aseries of gear-teeth O thereon, which mesh with similar teeth carried by the fixed wringer-roll C, while this roll is driven by aworm gear C", as shown in Fig.2. This gear when the frame is in its lowered position meshes with the threads of a worm D, mounted upon a driving-shaft D which is provided with a driving pu'lley D loosely mounted thereon,'and the shaft is supportedwithiu'suitable bearings D, carried. by brackets D extended from the standard Aat one side of the machine. Upon this shaft a sliding clutch D is suitably keyed and provided with teeth D adapted to engage corresponding teeth D carried by the driving-pullemas shown in Fig-'5, while the sliding clutch is adapted to he pivotally supported from a bracket 1) by means of the yoke D and shifted on the shaft through the handle D. This worm is suitably incased upon its under face and sides by means of a shell D to protect the same from contactwith the goods operated upon orfrorn injury in operating the machine, The worm-gear G is likewise protected-by means of a hood C extending over the outer face of the same and adapted to meetthe cas- A ing D, so as to inclose these parts. This hood is shown in detail at 4 and is supported by means of an arm by which it is attached to the swinging frame 0, and is pro vided with an extension 0 adapted to cover the upper portion of the worm D.

Above the fixed wringer-roll C an adjustable wringer-roll E is mounted, preferably, by means of a bearing E at each side of the frame, slidably mounted within a way E formed in the swinging frame, which bearing is adapted to be adjusted by means of a screw E mounted in the frame and acting against the pressure of a restoring-spring E beneath the bearing, so that the upper wringer-roll may be adjusted to secure the desired pressure for extracting the proper amount of moisture from the starched goods. The goods are fed through this machine by means of tapes or bands, as shown in Fig. 2, one series F of which extends from a tension-roll F downward over the upper wringer-roll and under the main starching-roll, thence between the wringer-rolls back to the tensionroll F, as shown by dotted lines in Fig. I,

while the other series F extends from abear-.

dotted lines in Fig. 1 and full lines in Fig. 2,

but are those usually employed in this character of machine and therefore not specifically illustrated and described. For the purpose of adjusting the tension-rollers F and F the frame 0 is provided with two horizontally-disposed ways F adapted to receive a l rectangular bearing-block F formed to fit closely and slide within the ways and having a lug F suitably threaded to travel upon the adjusting-screw F which is provided with a handle F to facilitate its operation, as shown in detail in Fig. 9, and each of the ways is v similar in construction.

upon the standardsfor instance, a link G asshown in Figs. '7 and 8. This link may be pivotally mounted within a lateral lug G lar lug G extending from the upper portion of the standards A, while a locking-handle G6 is pivoted bya pin G to the lower end of the link and'adapted to engage the under face of the lug G while all of the parts are inclosed and protected by means of a hood G secured to the lug G and extending downward, thus corrugations thereof thoroughly work the starch into the fabric, which is thence carried by the tapes upward between the wringerrolls, which extract the excess moisture, and

then delivered by the separation of the tapes in passing over their respective tension-rollers. It will be noted that all of the movable parts of this machine are mounted in the swinging frame, and therefore adapted to be instantly lifted from the starch-chest when desired, while the construction of driving gear permits this lifting without the necessity of shifting or disengaging any driving= belts and further provides a constant and steady driving motion best adapted to secure the'most eff cient results in this art.

It will be obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.

Having described our invent-ion and set forth its merits, what we claim, and desire to secure by Letters Patent, is-- 1. In a starching-machine, the combination with the framework and the tank thereof, of a swinging frame having central fixed and concentric sides and bottom bearings, amain and auxiliary corrugated intermeshin g starching-rolls mounted in said bearings, a wormgear mounted on the shaft of said main starching-roll, means for locking said frame in its lowest position, and a worm mounted on said i a E framework to mesh with the gear on the shaft The swinging frame 0 is providedbeyond its pivot with a foot G, adapted to rest upon 1 a portion of the delivery-table A when the frame is in its raised position, as shown in f detail in Fig. 3 and by dotted lines in Fig. 1. 5 The opposite end of the frame is provided; with a handle G for raising and lowering the same, and any desired means may be used. for connecting the swinging frame to the base i in the central fixed bearings of said swinging frame whereby said gear and worm are positively held in mesh when said frame is lowered.

2. In a starching machine, standards, a starch-chest supported between the same, a frame pivoted at one end above said starchchest, starching and wringing rolls supported entirely within said frame, a feed-table at one side of said frame, a delivery-table at the j opposite side thereof, a driving-shaft for said rolls mounted upon one of said standards, a from the frame by means of a pin G and is adapted to lie within a slot formed in a simisupporting-foot adapted to engage the table at the pivoted end of the frame, a securing device for the opposite end of said frame comprising a link pivoted to the frame and adapt-- edto enter a slot in the base upon which the frame rests, and a handle pivoted to the lower end of the link to engage said base; substantially as specified.

3. In a starching-machine, a pivoted frame adapted to support a fixed wringer-roll, exterior means for driving said roll, an adj ustable' wringer roll above the: same, a main starching-roller driven from the fixed wringerroll, auxiliary starchingsrolls concentric to.

adapted to support afixed wringer-roll,means for driving said roll, an adjustable wringerroll above the same, .a main starching-roller driven positively by gearing thereon from the wringer-roll, auxiliary starching-rolls concentric to and positively driven by gearing thereon fromthe main starching-roll, adjustable tension-rollers at one side of said wringerrollers, a tape or band passing over the upper wringer-roll, between the main and auxiliary starching-rollers and between the wringerrolls to a tension-roller, a lower tape or band passing between the starching-rollers and the wringing-rollers thence over a tension-roller separated from the first tension-roller, sliding bearings for said tension-rollers adapted to operate in parallel ways formed in the'frame and provided with a threaded lug projecting therefrom, and adjusting-screws mountedin the frame and passed through said lug; substantially as specified.
